DENVER—Jimmy and Rosalynn Carter as well as Garth Brooks and Trisha Yearwood are in Denver helping build and repair homes for Habitat for Humanity.

They picked up power drills and hammers Wednesday and joined other volunteers building 11 new townhomes and repairing 15 others.

In the evening, the former president will also attend a dinner celebrating the project at the National Western Events Center Arena. The lead singer of The Fray, Isaac Slade, is set to perform there.

Each year since 1984, the Carters have spent a week working on Habitat projects around the world. They also worked on a project in Oakland, Calif. this week and will head to New York City next to repair and renovate homes damaged by Superstorm Sandy.

The owners of Boulder’s Sterling University Peaks apartments, who this summer were cited for illegally subdividing 92 bedrooms in the complex, have reached an agreement to settle the case for $410,000, the city announced Thursday.
